Hi all,
I am using Intel i5-3337U processor. I want to get several perf events for a process via PID.
However when I am running perf stat command with several events for some seconds,in some execution its giving stats but sometimes its displayed all counters as "<not counted>"..
Could you please tell me the probable reason for that and how to get rid off this problem?

Hello,
Do you use VTune to import perf data? Could you please provide the exact command and OS name/version? It might be helpful for investigation.
Regards, Dmitry

Hi Dmitry,
No I am not using Vtune to get perf stats data, rather I am using only commands.
I am using Ubuntu 12.04 LTS ,(kernel version: 3.5.0-23 generic).
used command:
perf stat -e instructions,cycles,cache-

This is the forum for VTune Amplifier XE product.
I don't know why you can't use perf, but I know that perf can be used within VTune Amplifier, then import perf result into VTune
Please see the example in this article.
